Description

Technical Field

[0001] This utility model relates to the field of plastic product manufacturing technology, and in particular to an antistatic device for plastic products. Background Technology

[0002] The production of plastic products is a systematic process from raw material processing to finished product output, covering multiple stages such as raw material preparation, molding processing, post-processing and quality control. The raw material used in this production is plastic resin, with various additives added to adjust its properties. Finally, the plastic products are made through mixing. Due to their advantages of light weight, high plasticity and low cost, plastic products are widely used in human production and life.

[0003] During the production of plastic products, the poor conductivity of the plastic product surface makes it easy for a large amount of static electricity to accumulate. The accumulation of static electricity can harm production safety, equipment operation, and personnel health. Therefore, it is necessary to carry out static electricity elimination treatment. Most existing static electricity elimination devices for plastic products adopt a single ion fan structure. This device has a good effect on eliminating static electricity on a single surface of the plastic product, but the coverage of the ion fan is limited. During operation, it cannot automatically eliminate static electricity accumulated on other surfaces, which reduces the static electricity elimination efficiency and makes it easy for static electricity to remain on the surface of the plastic product, thus affecting product quality.

[0021] Please see the appendix Figure 1 Appendix Figure 4 and attached Figure 6 A sponge clamp 26 is fixedly connected to each adjacent side of a plurality of threaded rods 16. The top of the rotating column 14 is rotatably connected to the outer wall of the second rotating plate 27. A flow pipe 24 is connected to the front side of the collection box 205. A threaded cap 25 is threadedly connected to the front end of the flow pipe 24. A visible plate 23 is fixedly connected to the left side of the collection box 205. The top of the receiving plate 201 is slidably connected to the inner wall of the conveyor belt 7. Specifically, multiple threaded rods 16 are fixedly connected to sponge clamps 26 on adjacent sides. These sponge clamps 26 prevent plastic products from being damaged by direct contact with the threaded rods 16. The rotating column 14 and the outer wall of the second rotating plate 27 form a rotatable connection to ensure the stability of the rotation process.

In addition, a viewing panel 23 is fixedly connected to the left side of the collection box 205. It is made of transparent material to allow observation of the internal situation.

[0022] Working principle: When static electricity needs to be removed from plastic products, first screw the threaded rod 16 out through the screw hole 15 in the opposite direction. Then place the plastic product between the two opposite threaded rods 16 and screw the threaded rods 16 in the opposite direction. The plastic product is fixed by the sponge clamp 26. The controller 18 starts the first motor 4, which drives the two rotating shafts 5 to rotate, thereby driving the conveyor belt 7 to rotate. Under the action of the conveyor belt 7, the second motor 11, the first rotating plate 12, the connecting plate 13 and the rotating column 14 are transported into the inside of the outer shell 9. Then, by starting the ion fan 8, the surface of the plastic product is destaticated. The static electricity on the surface is eliminated, but at this time only the static electricity on one surface of the plastic product is eliminated. Then, by starting the second motor 11, the rotation of the second motor 11 drives the rotation of the first rotating plate 12, thereby driving the rotation of multiple connecting plates 13, so that the plastic product can rotate inside the outer shell 9, and the static electricity on multiple surfaces of the plastic product can be eliminated by the ion fan 8. The function of the insulating shell 17 is to protect the second motor 11 from being affected by the ion fan 8 and causing abnormal operation. By starting and stopping the rotation of the first motor 4, the time for the plastic product to eliminate static electricity can be controlled to ensure that the static electricity is completely eliminated. After static electricity is eliminated from the surface of plastic products, the surface can no longer adsorb small dust particles, causing these particles to fall into the device. This affects the device's static elimination efficiency and disrupts the cleanroom environment. Therefore, a dust collection structure 2 is needed to collect the small dust particles. After static electricity is eliminated, the small dust particles fall onto the surface of the conveyor belt 7 under gravity, and also fall into the receiving plate 201 through the second through hole 209 on the conveyor belt 7. By starting the dust pump 204, the dust is sucked into the collection box 205 through the bent pipe 203. When static electricity is eliminated... When the device stops working, to prevent small dust particles from being carried out of the collection box 205 by airflow, the handle 207 can be rotated to drive the shut-off valve 206, which will block the flow inside the bend 203. Then, the handle 207 can be locked into the limiting block 208 to restrict rotation. The connecting frame 210 and the curtain 211 can prevent dust inside the outer casing 9 from being carried into the external environment by airflow. The dust accumulation inside the collection box 205 can be observed through the viewing panel 23. The dust in the collection box 205 can be sucked out through the flow pipe 24 and the threaded cover 25.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
